Description

Technical Field

[0001] The invention relates to a dimensionally stable, soft and waterproof polyester wool-like sofa fabric and a preparation method thereof, belonging to the technical field of functional finishing of textiles. Background Art

[0002] As an important part of daily home, the choice of fabric directly affects the aesthetics, comfort and durability of the sofa. Polyester, as a kind of synthetic fiber, has become one of the common materials for fabric sofas due to its high strength, strong wear resistance and good elasticity. However, polyester fabric has poor moisture absorption and air permeability, and may cause stuffiness after long-term use. Moreover, once polyester fabric is woven with wool-like polyester, although it is more comfortable, it is more likely to generate static electricity and absorb dust, resulting in limited scope of use.

[0003] In order to improve the above problems, conventional polyester sofa fabrics are made by using special finishing agents and process flows, which are complicated to operate and difficult to be directly used for wool-like polyester fabric processing; moreover, the waterproofing agent used may contain fluorine, but is not environmentally friendly; in addition, the wear resistance and waterproof performance of the finished polyester fabric are very poor.

[0004] For example: CN115142261A discloses that the flexibility of polyester sofa fabrics is improved by using yarns with higher counts; the anti-pilling and anti-static properties of polyester fabrics are improved by doping with silver wire; the high flexibility, anti-fouling and anti-staining properties are improved by sucrose fatty acid ester and acetylation treatment; CN211518698U discloses a soft waterproof and breathable polyester fabric, which mainly includes a fabric body, a fabric base layer, a non-woven fabric layer, a cotton polyester layer, an inner layer and a waterproof layer, and improves waterproof and soft properties through a multi-layer structure; CN101956331A discloses a method for preparing a waterproof and breathable coated fabric, which specifically comprises the following steps: waterproofing a base fabric with a micromolecular waterproofing agent and a softener, and then coating the fabric with a polyurethane film having numerous micropores with a pore size between the diameter of a water droplet molecule and a water molecule by a microporous wet coating method, so that the prepared fabric has the advantages of both a high-density fabric and a microporous coated fabric, is soft in texture, and has high tear resistance and tear fastness, and also has excellent waterproof and breathable functions, and can well meet the market demand for waterproof and breathable fabrics.

[0005] Therefore, how to find a simple, soft and waterproof finishing process is an urgent problem to be solved. Summary of the invention
